Document Summary
Macroevolution: over long periods of time environmental isolation with genetic changes that lead to new species, hominin evolution. Microevolution: genetic changes over short, times with no environmental, isolation or speciation, human variation. Explaining how primate evolution happened: describing speciation. Using observed shared adaptations: assign fossils to a taxon (like species) by. 2 ways to give fossils and speciation dates: relative dating. How earth sediments are deposited over time: absolute dating. Primatology: study of nonhuman primates, two important kinds. Human taxonomy: primates, anthropoids, catarrhines, hominoids, hominids, hominins, humans, recent humans, amhs. Primate evolution begins 65 million years ago: what prompted evolutionary appearance of primates, meteorite, mass extinction, end of mesozoic era, cenozoic era begins, tropical climates develop. The eocene (54-38 m. y. a. : dominated by prosimians. Includes all monkeys and apes: continents split. Old world monkeys and apes: cattarhines. New world monkeys: flat nose, prehensile tail, lack full color vision. Old world monkeys and apes: catarrhines, forward noses, full color vision.
